BALE=EJECTOR FOR BALlNG-PRESSES.

$PECIFICATION forming part of Letters Patent No. 31%,523, dated MarchApplication filed August 27, I884. No model.)

T all whom. it may concern.-

Be it known that I, JOHN LUM DUVA-L, of Houston, in the county of Harrisand State of Texas, have invented a new and useful Improvement inBale-Ejectorsfor BalingPresses, of which the following is a full, clear,and exact description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a front elevation of the head block and follower of abaling-press. Fig. 2 is a sectional end elevation of the same, takenthrough the broken line m m, Fig. 1. Fig. 3 is a sectional end elevationof the upper part of the follower enlarged, and showing in sideelevation a truck in its channel. Fig. 4 is a sectional end elevation ofthe same, taken through the broken line 3 y, Fig. 3. Fig. 5 is a planview of the truck.

The object of this invention is to provide a mechanism for attachment tobaling-presses provided with a follower moving upward to compress thebale, for removing the bale from the press, and operated by the movementof the follower as it moves downward with the compressed bale.

The invention consists in the combination, with a baling-press followerhaving channels with inclines and recesses at their rear ends, of trucksprovided with ropes or chains, pulleys, pulley-segments having arms, andsta tionary arms for drawing the trucks forward, and with ropes orchains, pulleys, and weights for drawing the trucks rearward. The truckshave recesses with inclined shoulders in their sides to receive prongshaving front and rear shoulders, and attached to pins pivoted to thesaid trucks, as will be hereinafter fully described.

A represents the head-block, and B the follower, of a balingprcss, aboutthe construction and operation of which there is nothing new.

0 represents the rods connecting the follower B with the power by whichit is operated.

In the top of the follower B, at ,the bottom of two or more of thegrooves for the balebands, are formed channels D to receive the trucksE.

In the bottoms of the channels D, at the rear side of the follower B,are formed recesses F to receive the trucks E, and from which inclines Glead to the bottoms of the said chan nels D. The recesses F are made ofsuch a depth that when the trucks E are in them the points of the prongsH will be below the bot; toms of the channels D, so that they will notcome in contact with the covering of the bale. The prongs H are placedin recesses I in the sides of the trucks E, and are attached to the endsof rods J, passing through and pivoted in the said trucks. with inclinedshoulders K at their rear sides, for the rear shoulders L of the prongsH to rest against when the points of the said prongs are raised, andwith inclined shoulders M at their forward sides for the forwardshoulders N of the said prongs to rest against when the said prongs arelowered. The shoulders K L are so formed that the prongs H, when raised,will stand at an angle of about forty-five degrees, as shown in Fig. 3,and the shoulders M N are so formed that when the prongs H are loweredtheir points will rise a little above the tops of the trucks E, as shownin Fig. 2.

To the forward ends of the trucks E are attached,byscrew-eyes O or othersuitable means, the ends of chains or wire ropes P, which pass forwardalong the channels D, pass over guide-pulleys Q, pivoted to supportsattached to the forward side of the follower, and are attached at theirlower ends to the lower corners of the segments B of grooved pulleyspivoted to the said forward side of the follower B. The segments R areprovided with arms S to engage with stationary arms or toes T, attachedto posts U, forming apart of support to platform or door in front ofpress.

To the rear ends of the trucks E are attached, by screw-eyes V or othersuitable means, the ends of chains or wire ropes XV, which pass overguide-pulleys X, pivoted to supports attached to the rear side of thefollower B, and to their other ends are attached weights Y, ofsuflicient gravity to draw the trucks E back to the recesses F when thebale has been discharged. The lower sides of the forward ends of thetrucks E are beveled, as shown in Fig. 3, so that the said trucks whendrawn forward will readily pass up the in The recesses I are made clinesG, and the said trucks may be mounted upon small wheels or rollers, ifdesired, to cause them to move with less friction than when they slidethrough the channels D. \Vith thisconstruction, as the follower B movesupward in compressing a bale the upper sides of the arms S strikeagainst the lower sides of the arms T, which swings the segments Rupward until the arms S have passed the arms T, when the said segmentsdrop back into their former positions.

When the bale has been compressed and bound, and the follower B beginsto move downward, the arms S strike the arms T, which swings thesegments R downward, and causes the ropes or chains P to draw the trucksE forward. As the trucks E move up the inclines G to the bottom of thechannel D, the points of the prongs H strike the bale, are turned upwardinto the position shown in Fig. 3, and then carry the bale forward untilit projects so far in front of the press as to overbalance and fall tothe floor. When the follower has moved so far down that the arms S leavethe arms T, the trucks E are drawn back to the recesses F by the weightsY, and the follower is ready to press another bale. The lower sides ofthe forward ends of the trucks E are beveled, to cause them to pass upthe inclines G readily.

If desired, the trucks E can be provided with small wheels or rollers tolessen the friction as they move back and forth.

Having thus described my invention, Iclaim as new and desire to secureby Letters Patent- 1. The combination, with the follower B of abaling-press, having channels D, recesses F, and inclines G, of thetrucks E, having prongs H, and an operating mechanism, substantially asherein shown and described, whereby the compressed bale will be removedfrom the press, as set forth. v

2. The combination, with the follower B of a baling-press, havingchannels D, recesses F, and inclines G, of the trucks E, the ropes orchains 1?, pulleys Q. segments R, having arms S, the stationary arms T,and the ropes or chains W, pulleys X, and weights Y, substantially asherein shown and described,whereby the said trucks will be operated fromthe movements of the said follower, as set forth.

3. In a bale-ejector for ba ling-presses, the trucks E, constructed,substantially as herein shown and described, with recesses I, havinginclined shoulders K M, and provided with the rod J, and the prongs H,having shoulders L M, as set forth.
